Exceptional Pressure Range up to 10,000 bar
The defining characteristic of the europascal CH3-10000B is its exceptional pressure range:
0 to 10,000 bar
or approximately:
0 to 145,000 psi.
This places the CH3-10000B above conventional hydraulic pressure comparators and makes it suitable for highly specialized calibration tasks.
Pressure instruments used in sectors such as automotive development, materials testing, hydraulic component manufacturing, research and high-pressure process technology can operate at pressures far above the ranges covered by conventional calibration pumps.
The CH3-10000B provides a dedicated solution for these applications.
Designed for Very High-Pressure Calibration
The CH3-10000B was specifically developed for very high-pressure calibration.
The manufacturer’s current pressure portfolio separates its comparison systems into three principal groups:
- Eco and Standard comparators
- High Performance comparators
- High Pressure CH3 comparator
The CH2 high-performance hydraulic series extends to 7000 bar, while the CH3-10000B extends the comparison range to 10,000 bar.
This makes the CH3-10000B the appropriate platform when the required calibration pressure exceeds the capability of the standard CH2 high-performance series.
Hydraulic Pressure Generation
The europascal CH3-10000B operates hydraulically.
Hydraulic pressure generation is particularly suitable for very high pressures because liquids have very low compressibility compared with gases.
The pressure medium used by the CH3-10000B is oil. Depending on the application and configuration, the manufacturer specifies mineral or synthetic oils for the CH3 platform.
Before connecting a device under test, the operator must ensure that its pressure-wetted components are compatible with the selected hydraulic medium.
Three-Piston Pressure Generation System
A particularly important technical characteristic of the europascal CH3-10000B is its:
three-piston system.
Generating pressures up to 10,000 bar manually requires a specialized pressure generation concept.
The multi-stage piston arrangement enables pressure to be increased progressively to the required ultra-high-pressure level.
The current technical datasheet specifies three pistons for the CH3-10000B.
This distinguishes the CH3 from lower-pressure comparator platforms and reflects the special mechanical requirements of 10,000 bar pressure generation.
125 cm³ Hydraulic Reservoir
The CH3 platform incorporates a hydraulic fluid reservoir with a volume of:
125 cm³.
The reservoir supplies the hydraulic medium required to fill and pressurize the calibration system.
The visible fluid level allows the operator to monitor the available pressure medium during operation.
Correct filling and clean hydraulic fluid are particularly important for high-pressure calibration systems.
61 cm³ Displaced Fluid Volume
The pressure generation system can displace a maximum fluid volume of:
61 cm³.
This provides sufficient hydraulic displacement for filling the connected pressure system and generating the required pressure.
The actual pressure behavior also depends on the internal volume and elasticity of the connected device under test, adapters and pressure lines.
At very high pressures, minimizing unnecessary internal volume and using components specifically rated for the pressure range are essential.
Comparison Calibration Principle
The europascal CH3-10000B is designed for calibration by comparison.
The basic measurement principle is straightforward:
A calibrated reference pressure instrument and the device under test are exposed to the same hydraulic pressure.
The generated pressure is measured using the reference instrument.
The indication or output of the device under test is then compared with this reference value.
The deviation can be expressed as:
Deviation = DUT indication – Reference value
This principle allows the CH3-10000B to be combined with different reference instruments depending on the required calibration uncertainty and pressure range.
Calibration of High-Pressure Gauges
One of the primary applications of the europascal CH3-10000B is calibration of high-pressure gauges.
These can include:
- Analog high-pressure gauges
- Digital high-pressure gauges
- Reference pressure gauges
- Industrial pressure indicators
The reference instrument and device under test are connected to the comparator.
Defined calibration pressures are generated and the two indications are compared.
Measurement points can be approached with increasing and decreasing pressure according to the applicable calibration procedure.
Pressure Sensor Calibration
The CH3-10000B is particularly suitable for calibration of high-pressure sensors.
The manufacturer specifically identifies transducer calibration as an important application for the 10,000 bar comparator.
The comparator generates the hydraulic pressure while a suitable electrical measuring instrument measures the sensor output.
Depending on the sensor design, typical outputs may include:
- mV/V
- Voltage
- Current
- Digital signals
This enables the complete pressure-to-electrical characteristic of the sensor to be evaluated.
Pressure Transmitter Calibration
High-pressure transmitters can also be calibrated with the europascal CH3-10000B.
The comparator provides the pressure input while a reference pressure instrument determines the applied pressure.
An electrical calibrator or precision multimeter measures the transmitter output.
For industrial transmitters, this may be a standardized:
4–20 mA
or voltage signal.
The relationship between reference pressure and transmitter output can then be evaluated across the required measuring range.
Pressure Switch Testing
The europascal CH3-10000B can also form part of a test setup for high-pressure switches.
Pressure is increased until the switch changes electrical state.
The corresponding pressure is determined using the connected reference instrument.
The pressure can subsequently be reduced until the switch resets.
This allows determination of:
- Switching pressure
- Reset pressure
- Switching hysteresis
Suitable electrical instrumentation is required to monitor the switching contact.
M20 × 1.5 Pressure Connection
The current CH3 technical specification identifies the connection for the device under test as:
M20 × 1.5 female adapter.
For instruments with different pressure connections, suitable high-pressure adapters are required.
At pressures approaching 10,000 bar, only components specifically designed and rated for the corresponding pressure should be used.
This includes:
- Adapters
- Fittings
- Tubing
- Valves
- Seals
- Reference instruments
- Devices under test
Robust Construction
The europascal CH3-10000B is designed for demanding professional use.
The housing is manufactured from:
AG3 light-alloy aluminum
and protected by:
high-resistance paint.
The mechanical construction is designed to provide a stable platform for ultra-high-pressure generation.
The capstan can be removed for transport.
Integrated Leveling System
The CH3-10000B incorporates:
a leveling bubble
and:
adjustable feet.
This enables the instrument to be correctly aligned on the laboratory bench.
Correct positioning is particularly important because the CH3 platform also forms the generator base for the related BH5-10000B deadweight tester.
Operating Temperature
The specified operating temperature range is:
18 °C to 28 °C
or:
64 °F to 82 °F.
The manufacturer states that its pressure benches are tested under reference conditions of approximately:
20 °C temperature
1013.25 hPa atmospheric pressure
50% relative humidity
and:
9.80665 m/s² gravitational acceleration.
Environmental conditions should be considered when performing high-accuracy pressure calibration and establishing the measurement uncertainty budget.
Compact Solution for 10,000 bar
Despite its exceptional maximum pressure, the europascal CH3-10000B remains a relatively compact laboratory pressure generator.
The current datasheet specifies a comparator weight of approximately:
30 kg.
This is particularly noteworthy given the 10,000 bar maximum pressure capability.
The compact design allows the system to be installed on a suitable laboratory bench without the extensive infrastructure traditionally associated with some ultra-high-pressure generation systems.
Development of the 10,000 bar Platform
The 10,000 bar platform represents a significant development within the manufacturer’s pressure metrology range.
Research and development of the very high-pressure system took place during 2017 and 2018, followed by commercialization of the 10,000 bar deadweight tester and comparison bench in 2020.
The manufacturer reports that development required several years of research and testing.
The resulting technology has been evaluated through calibration work performed by national laboratories.
From CH3 Comparator to BH5 Pressure Balance
The CH3-10000B is closely related to the BH5-10000B high-pressure deadweight tester.
The current BH5 specification explicitly identifies:
CH3-10000B
as the generator base of the BH5-10000B.
This provides an important upgrade path for laboratories.
The CH3 can initially be used as a comparison pressure generator together with a suitable reference pressure instrument.
For applications requiring a pressure balance principle, the corresponding BH5 system adds the piston-cylinder assembly and mass system required to generate pressure from force and effective piston area.
BH5-10000B High-Pressure Standard
The related BH5-10000B pressure balance covers:
200 to 10,000 bar
or:
3000 to 145,000 psi.
The BH5 uses the CH3-10000B as its pressure generator.
One of the particularly innovative aspects of the BH5 concept is its ability to generate 10,000 bar with only approximately:
50 kg of masses.
This demonstrates the specialized high-pressure technology on which the CH3/BH5 platform is based.
Applications in Industry and Laboratories

High-Pressure Safety
Pressure levels approaching 10,000 bar require a calibration system specifically designed for ultra-high-pressure operation.
All pressure-wetted components must be suitable for the applied pressure and medium.
Particular attention must be paid to:
- Maximum permissible working pressure
- Correct fittings
- Correct tightening procedures
- Condition of pressure lines
- Hydraulic fluid compatibility
- Condition of seals
- Protection of operators
- Controlled pressure release
- Manufacturer operating instructions
Only trained personnel should operate ultra-high-pressure calibration systems.
Metrological Traceability
The CH3-10000B acts as the hydraulic pressure generator in comparison calibration.
Metrological traceability is established through the calibrated reference pressure instrument and the complete documented calibration procedure.
The manufacturer states that its own calibration laboratory is equipped with reference standards allowing pressure checks up to 10,000 bar.
For users requiring a primary pressure standard rather than comparison against a reference gauge, the related BH5-10000B pressure balance provides the corresponding deadweight tester solution.
